This study are developed to predict the permeability of Tertiary reservoir in Khabaz oil field northern of Iraq. The Tertiary reservoir include many geological formations (Aaliji, Jaddala, Oligocene system, Jeribe, Fatha, Muqdadia formations). Actually Seven wells (Kz-1, Kz-2, Kz-3, Kz-4, Kz-9, Kz-14, Kz-15) used for this study in Khabaz oil field. Two methods are used, which are classical methods depending on core test and well log interpretations and FZI methods, the results show that the permeability estimated by core and well log interpretation method which depending on just the porosity are not close enough for the real values because it’s not toke in the consideration all the parameters that effect the values of permeability.
The FZI method are show more real values and provides best correlation coefficient in comparing with the classical methods. The must conclusions of the result refer that the FZI method results are more accurate because of the high correlation coefficient (R2) values.
